Numerical Investigation of Fire Safety of an Indoor Pedestrian Street

With the development of economy, indoor pedestrian streets have become more and more popular in large commercial architectures. The safety of such type of construction has drawn people´s attention. Traditional methods for fire protection are difficult to meet the requirement in indoor pedestrian streets due to the large span of the building. Investigation is needed to evaluate and improve the fire safety level of such place. This paper adopts FDS (Fire Dynamic Simulator) to simulate fire development of an indoor pedestrian street in a most recently designed large-scale shopping mall in China. The influences of fire locations, smoke extractions, and fire-extinguishing systems on fire development were mainly studied. According to the simulation results, appropriate fire protection methods were discussed to ensure the safe evacuation, which gives reference to fire protection design of similar buildings.
